Proteins and Enzymes Flashcards
Protein can be three things, what are they?
Fibrous, Globular and Conjucated.
What dies the sequence of bases in a DNA molecule determine?
It determines the structure, shape and function of a protein.
Give examples of Fibrious?
Collagen and Keratin.
Give examples of Globular?
Enzymes, antibodies, hormones and structural membrane proteins.
Give an example of Conjucated?
Haemoglobin.
What are Enzymes?
Enzymes are biological catalysts that are made by living cells.
What is the function of Enzymes?
Speed up chemical reactions but remain unchanged.
What is the area on the enzyme where the reaction takes place?
The active site.
The shape of the active site is specific to the?
Substrate.
What are the conditions that the enzyme is most active?
Optimum conditions.
What affects the rate of an enzyme reaction and what can it result?
PH and temperature affects the rate of enzyme reaction this can result in changes to the shape of the enzyme.
What can denature an enzyme and what can this result in?
High temperatures can denature an enzyme this results in a change to the shape of the enzymes active site.
Enzymes can be involved in either Synthesis Reactions or Degradation Reactions. What is synthesis reactions?
Building small molecules into larger ones.
What is Degradation reactions?
Breaking down large molecules into small ones.
